The SmartMaxx™ controllers work similar like thermistors but there is a little difference in the way of measuring the temperature. The Pt1000 sensors (type of sensor which are using our systems) are also called RTDs. The resistance temperature probe is based on the resistance of metal in our case Platinum. The resistance of this metal depends on the temperature. Basically there are two types of thermistors PTC (the resistance is increasing due to temperature growth) and NTC (an increase in temperature causes the resistance to decrease) – the value of resistance depends on temperature. These type of sensors are more sensitive than basic type of controllers.
Is The Sensor For The SmartMaxx™ Controller a Thermocouples or Thermistors?Dawid P
